Multiple flaws have been identified in Linux Kernel and related software could allow hackers to hack your Linux machines, shared hosting and websites hosted on them. PRIVILEGE ESCALATION VULNERABILITY IN LINUX KERNEL A privilege escalation vulnerability has been identified in the widely used Linux kernel that could allow an attackers to take the control of users' system. On Thursday, the most popular distributor of open source Linux OS, Debian warned about this vulnerability (CVE-2014-3153) in a security update, along with some other vulnerabilities in the Linux kernel that may lead to a denial of service attack. The most critical one is the flaw (CVE-2014-3153) discovered by Pinkie Pie which resides in the futex subsystem call of Linux Kernel 2.6.32.62/3.2.59/3.4.91/3.10.41/3.12.21/3.14.5 versions , leaving a queued kernel waiter on the stack, which can be exploited to potentially execute arbitrary code with kernel mode privileges.

Underground sites more commonly offer access to networks of compromised machines or stolen credit card information. Webroot has uncovered a criminal underground store dedicated to selling access to more than tens of thousands of hacked legitimate websites. Their customers can buy an administrator account or shell access in a hacked website, at cheap price i.e. $0.5 to $10 and then allows to perpetrate criminal activities from it, distribute malware, install a botnet  command & control infrastructure, upload illegal content, send spam, and so on. In Screenshots Researchers shows an underground market proposition, whose inventory is currently listing over 6000 compromised/hacked shells internationally. Sites are listed based on the price, page rank, age of the domain, Alexa ranking, language, and number of pages indexed by Google. The site promised access to any number of the compromised websites and the store seems to be quite profitable....

As a relatively new security category, many security operators and executives I've met have asked us "What are these Automated Security Validation (ASV) tools?" We've covered that pretty extensively in the past, so today, instead of covering the " What is ASV?" I wanted to address the " Why ASV?" question. In this article, we'll cover some common use cases and misconceptions of how people misuse and misunderstand ASV tools daily (because that's a lot more fun). To kick things off, there's no place to start like the beginning. Automated security validation tools are designed to provide continuous, real-time assessment of an organization's cybersecurity defenses. These tools are continuous and use exploitation to validate defenses like EDR, NDR, and WAFs. They're more in-depth than vulnerability scanners because they use tactics and techniques that you'll see in manual penetration tests. Vulnerability scanners won't relay hashes or combine vulnerabilities to further attacks, whic
